Rather than describing the increased kinetic energy of the stone to the work of gravity, we now (when using potential energy rather than work-energy) say that the increased kinetic energy comes from the ______ of the _______ energy.a) work / potentialb) force / kineticc) change / potential

Answer :

The increased kinetic energy of the stone comes from the change of the potential energy

Explanation:

  • Potential energy depends on mass, gravitational force, and height.
  • When the stone is at rest it has potential energy.
  • When the stone falls or is subjected to the work of gravity its potential energy is changed to kinetic energy.
  • The total energy of the object remains constant that is the decrease of the potential energy is an equal increase in the kinetic energy.
  • Hence, the increased kinetic energy of the stone comes from the change of the potential energy.
